This invention relates to door operating mechanisms and pertains particularly to mechanisms designedto permit simultaneous operation of a plurality of doors.

Itis an'object of theinventionvto provide a mechanism which shall be extremely sim-' ple in its construction and operation, but

' which will operate positively and easily all times.

Other objects and advantages of the invention will appearhereinafter.

'A preferred embodiment of the inventionv selected for purposes of illustration is shown in the accompanying drawmgspm which, Figure 11s a top plan view of the mechanism as applied to a pair of garage doors, the

roof of the garage being removed; to better disclose the construction and operation of the mechanism; H j Figure 2 isffl section on the line 2-2 of Figure 1'; V

Figure 3 is an enlarged detail sectional view of the traveller member Figure 4 is a section on the line 4-4 of V Figure 3, and

Figure 5 illustrates the method of attaching the arms to the traveller member when connected to open both doors to the same ex- .tent.

Referring to the drawings, the apparatus comprises a guide member 1, preferably of a shallow channel form which may be secured to the tie beams 2 or ceiling of the building in any suitable manner. Mounted for reciprocation along'the guide 1 is a traveller member 3'Which preferably comprises a U- hinges from the reciprocatory member 3,

rigid links 9 and 10, which may be of channel iron,preferably forming the connection 1929. Serial in; s'4ac24f I d between the member 3 and the doors; The connection of the links with thedoo'rsmaybe secured by pivot-pins 11 and with the mem: her 3 bya-kingpin'12." If both doors are to be opened 'to thesamean'gular extent thelinks 9*and 10 may both be connected to thelzing pin 12 as'illustrated in Figurefil'; 'Lo'cknuts 1e retain the-links-upon-theking ping" 1 I But it maybedesirable"tofopenbneof the doors to'a greaterangular 'extent than the other. This will'be the case, for example, when the line'of access to" the doors is not at right angles to the plane of the doors when closeded; e. to theplane of th'e'cpeningbut is inclinedto one side or the other. In this case the operating mechanism isasseinbled in L Heifiitis seen that, theli'nk -10 has'ebeen shifted 5 and one end-which :may be 3 designated the inner end-pivotedto theother'link 9 while the other-or outer end hasbe'en movefd nearer-the hinged edge-of thedoor; V I To provide fonthisiselective assembling *or ustability of partsy each link near its inner'end is formed with a' series "of holes 16 and the other link is pivotall'ysecured at a selected nasty a bolt 17 and lock n'uts 18 the manner'illustrated in Figures 1, Sand 4 7 As illustratedin F igure l the link" "10- is secured at its end to "link 9; but it will be apparent that theend of link 9 m ay'be similarly secured to link 10 when it is necessary to open the other door wider. 1 r I 1 At the outenendsof the links wherethey are attached to the doors, the adjustable connection is secured through pivot bars 1 5; Thesebar's i may be of angle-form with-their vertical flan es secured toth'e' door and "their horizontal auge formed with a series of holes 1 3 'forpivot ibo-lts 115 g eithenopen'or closed position.- Referring to Figures 3 and '4; vmounted on the U-shaped member t'i's a transverse shaft 18 pivota lly supporting a-lat'ch member lt) havingado-wnwardly extending prong 20 and "ail, upward 1y extending arm 21. The latch 19 is nasal- 's provided for holding the doors 7 anced on the shaft 18 so thatthe' prong 20 normally rests on the'tottom-ef the'channelshaped guidemember 1, and the guideinem beris provided (see also Figurel) with'suiti ably positioned apertures 23 into which the prong may drop in order to hold the doors in any desired position of adjustment. Preferably one of the apertures 23 is located near the outer end of the guide 1 in proper position to hold the doors open, while the other aperture 23 is located near the inner end of the guide member in proper position to hold the doors closed.

In order to release the latch 19 so that the doors may be opened-or closed asthe case 7 may be, a suitable pull-cord 24 may be secured to the arm 21, and the free end'of the said pull-cord led to any desired position for convenient operation, preferably to one of the, doors. r. r

In installing the apparatus,v the guide member is first secured in the desired position to the travelling member as the case may be,

the doors may be, caused to open more or less widely asdesired. When it is desired that the doors shall both open to the same degree, the arms 9 and lO'are connected to the traveller member?) through the bolt 12, but when it e is desired that one of the doors shall open more widelythan theother, one of the arms is connected to the other armin such position as toigive the desired variation, and the other arm alone is connected to the bolt 12.

r In operation, assuming that the doorsare open as illustrated in Figure 1, the pull-cord 24 is drawn forward to cause the'latch 19 to be disengaged from the aperture 23, after which oneor the other of the doors is moved in closing direction, As will be observed, movementof one of the doorsis sufficient to cause simultaneous movement of the other door in unison therewith, and if the doors havebeenproperly installed, closure of the two doors will be effected simultaneously. When the doors are fully closed, the latch 19 ordinately openingeach of said doors selectively by various degrees but closing the doors always to the same position, said means including a travelling member movable at right angles to the plane passing through the hinge axes of said doors, links connected at their outer ends with said doors and operatively connected with said travelling member at their inner ends, transverse strips having a series of elements providing adjustable pivotalattachment for the outer ends of said links tothe doors, a king pin forming the connection tor-one of said'links, or when desired for both of said links, with said travelling member, said links at their inner ends being provided with a plurality of adjustment holes, and apivot pin for securing one link upon the other in adjusted positions when the other is secured by said king pin. v I
